The folks at YouTube announced today that they are launching "YouTube Insight", a free tool that enables anyone with a YouTube account to view detailed statistics about the videos that they upload to the site. For example, uploaders can see how often their videos are viewed in different geographic regions, as well as how popular they are relative to all videos in that market over a given period of time. You can also delve deeper into the lifecycle of your videos, like how long it takes for a video to become popular, and what happens to video views as popularity peaks.
you can find currently available metrics by clicking under the "About this Video" button under "My account > Videos, Favorites, Playlists > Manage my Videos." You can see how many times your video has been viewed by date, and there is also a map of the world showing in which countries your video has been viewed.
